Abstract
A sensing element for measuring extracellular potential including a substrate, a well provided in a substrate, a guide section provided on the wall of the well, and a detective electrode formed at a lower surface of the substrate. The guide section is for guiding drug. The well is provided at the bottom with a depression, and a first throughhole penetrating through the depression and the lower surface of the substrate. The well is for mixing a subject cell, a culture solution and the drug together. The above-configured sensing element accurately measures a change generated by a subject cell.
Claims8
A device for measuring extracellular potential comprising:
- a sensing element including:
- a substrate;
- a well having a bottom and a wall, provided at the substrate for holding a subject cell, a culture solution and a drug together therein;
- a guide section provided on the wall for guiding the drug into the well and having a channel for mixing of the drug with the culture solution;
- and
- a detective electrode provided below the substrate, wherein
- a depression and a first throughhole penetrating through the depression and a lower surface of the substrate are provided at the bottom;
- a case of the device, contacting with the well and provided with a second throughhole penetrating through the case in a radial direction such that the second throughhole penetrates to the well to expose the depression;
- and
- a tube inserted in the second throughhole, provided for dispensing either the culture solution or the drug into the case.
